4A Metal Telescopic Dilator (Alken Dilator Set)
The Metal Telescopic Dilator (Alken Dilator Set) is a classical, highly rigid endourological access system used to establish percutaneous nephrostomy tracts during PCNL. Consisting of a central guide rod and a series of stainless steel tubes that nest over one another, it provides high mechanical force to dilate dense scar tissue and thick flank muscle.
